With direct evaporative cooling, outside air is blown through a water-saturated medium (usually cellulose) and cooled by evaporation. The cooled air is circulated by a fan.

Direct evaporative cooling adds moisture to the air stream close to saturation. Then dry bulb temperature is reduced, while the wet bulb temperature stays the same.

Indirect Evaporative Cooling
With indirect evaporative cooling, a secondary air stream is cooled by water. The cooled secondary air stream goes through a heat exchanger, where it cools the primary air stream. The cooled primary air stream is circulated by a fan. Indirect evaporative cooling does not add moisture to the primary air stream. What is IDEC Evaporative Cooling?

IDEC Evaporative Cooling is a 2 stage evaporative cooling system

Using potable water – (or Grey Water)

1st stage water is cooled via a indirect heat exchanger allowing us to pre cool the air with no added moisture at approx.80% efficiency

Insulated shut off damper

Benefits:

Constructed with aluminium aerofoil insulated blades with polyurethane foam tested in accordance with BS 7456 and having Class 1 surface spread of flame with a u value of 0.02w/m.
Dampers are constructed to low leakage specification with tight blade and edge seals

Auto change over control system for duty and stand by operation on VTI units

Bottom and side access

Envirofresh and Classvent

Packaged units such as Envirofresh and Classvent units are pre commissioned at the factory prior to despatch. The units are factory pre-wired and complete with a comprehensive control system, to minimise on site installation time. All units provide full fresh air ventilation with a heat recovery device to increase the temperature of the incoming fresh air and are fully compliant with the European Directive ErP 2016 (Energy Related Products) for electrical engines and fans.

Application

Combine with other systems such as VRV and chilled water fan coils to provide tempered fresh air.

Where occupant fresh air requirement exceeds design cooling volume.

Available with volumes from 0.5m3/s to 7.0m3/s

Acoustic Test Programme to BS EN ISO 10140 2:2010

During 2013 the company embarked on an Acoustic Test Programme for twenty different frame/panel systems and have them certified to BS EN ISO 10140 2:2010 International Standard Method for Measurement of Sound Test see Report 1429/2060

ErP Directive document 2016

Air Handlers are committed to the energy reduction commitments laid down by the Energy Related Products (ErP) Directive 2009/125/EC law which comes into force on 1st January 2016 with further changes on 1st January 2018.

Ecodesign directive is integral to the European Union’s commitment to reaching a 20% reduction in greenhouse gas emissions and energy consumption by 2020.

Air Source Renewable Energy Solutions

Air Handlers are pro-active in understanding the changes to building services low energy specifications and this has led to the development of the Classvent range of Low Noise / Energy products specifically designed for schools, colleges and universities. This product was the first ceiling mounted heat recovery unit to incorporate summer boost ventilation, recirculation dampers for fast room warm up on start up, fully automated control and connection to BMS control.

Our team of research professionals are committed to developing products with sustainable energy solutions to meet the challenge of the ECO DESIGN Directive which is the European Union's commitment to reaching the 2020 goals, by aiming to reduce Greenhouse Gas Emissions by 20% and overall energy consumption by 20%.
